Noticed Major Slayer was not showing up. Went into Ilessen Tower, Bad Man`s Hollow, Spindleclutch and Cloudrest to confirm and it is not showing Major Slayer. However Minor Slayer is showing in Spindleclutch and Cloudrest.
Slayer buffs only apply in 4 man group dungeons, arenas and trials. You won't get the buff in overland content.
Well, it’ll show the buffs in overland (with the S’rendarr addon anyway), it just won’t do anything
I’m assuming OP is using base game buff tracker. Possibly they’re overlooking the buff icon while in a dungeon since there’s usually a shton of buffs applied.
